In this paper, we improve the Proinov theorem by adding certain rational expressions to the definition of the corresponding contractions. After that, we prove fixed point theorems for these modified Proinov contractions in the framework of dislocated b-metric spaces. We show some illustrative examples to indicate the validity of the main results. 2021-04-26T09:59:25Z 2021-04-26T09:59:25Z 2021-03-10 journal article Alqahtani, B., Alzaid, S.S., Fulga, A. et al.
